How long it takes to review the enlarged lymph nodes depends on the specific situation. If it is caused by physiological factors, usually no review is needed; if it is a benign disease, usually a review is needed once every half a year; if it is a malignant disease, then it should be treated immediately. Some thin people may have lymph nodes in superficial parts of the body, such as the neck, which are generally physiologic and need not be overly concerned after disease is ruled out, and usually do not need to be reviewed. If the lymph nodes are caused by benign diseases, such as tuberculosis and lymphadenitis, the examination is usually done once every six months. At the time of review, through physical examination, dynamic observation and ultrasonography of lymph nodes, etc., the edge pattern of lymph nodes, their growth, and the surrounding vascular structure can be clarified. If undesirable changes are found in the lymph nodes, the doctor can decide whether removal biopsy or prophylactic resection is needed. If it is caused by malignant diseases, such as metastasis of malignant tumors and lymphoma, a comprehensive examination should be carried out immediately under the guidance of the doctor to clarify the cause of the disease and formulate a comprehensive treatment plan. Patients with enlarged lymph nodes that do not go away should follow the doctor’s instructions for regular rechecks, and if progressive enlargement of lymph nodes is found, they should also be rechecked in time.
